Antimicrobial Activity of Tannic Compounds

The view that tannic compounds have the main function against the microbes including plant pathogenic microbes and non pathogenic microbes,The important factors that influence that ability of tannic compounds to microor-ganisms is the tannin polymer size.In practice,the toxicity of tannins is always dynamic.The tannin monomers polymer-ization can improve the toxification,while the tannin oligomers polymerization can lead to the detoxification.
